A. ALLTIMES CUTTING lAND EMBOSSING DEVICE FOR BISCUIT MACHINES Filed Oct. 15, 1926 placed by one in which other forms are used.

To the bedplate l5 are secured the embossingblocks 2O and the cutters 21, by means of the bolts 200 and 210 respectively, in corresponding multiples, the embossing blocks in such relation to their respective cutters that the surface embossed in one cycle is severed by the corresponding cutter in the next. Slidably mounted on each of the embossing blocks is a stripper 22, provided with lugs 23, projecting from which, upwardly, are the studs 24, which serve as arbors for the springs 25. The bed plate is formed With holes through Which the springs and studs may pass, and the studs are slidable in a plate 26, which is adjustable relative to the face of the bed vplate 15, a means for such adjustment and securing the plate in adjusted position, being shown, inwhich the studs 27, rigidly projecting up Wardly from the bed plate 15, are threaded at their upper ends to receive the nuts 270. The plate 26 is perforated to permit the passage therethrough of these studs, and by means of the nuts 270, the plate may be adjusted relative tothe surface 2O:l of the embossing block 20. The studs 24 are also threaded at their upper ends to receive the nuts 28, by means of which each stripper may be independently adjusted longitudinally with its particular embossing block and in relationto the plate 26.

The stripping edge 29 is adjusted so that as the crosshead is reciprocated to operate the embossing unit, the stripper acts as a presser to contactv with the dough sheet before the embossing face a, yielding through the means described, and on the return movement.` the embossing face is Withdrawn before the stripper edge releases the dough sheet. As the action of the machine is rapid relative to the movement of the dough, there is no tendency for the dough to bank on the stripper While it is in contact.

This isa departure from existing methods,

- and the present tendency for the embossing block to lift the dough, is overcome; this forms an important feature of my invention as a means. of overcoming distortion and banking of the doughy sheet, and operates to increase both economy and eticiency by permitting a more rapid action of the device. The cutter corresponding with each embossing unit, is provided internally with a plunger 30,r from which extends upwardly, the stud 3l, slidable in the bedplate 15, and secured at its upper end to a plate 32, above the bed plate and Within ribs 330' formed on the bed plate. The lower faces of the several plungers are so positioned that they are in the plane of the stripping face of the clearer 33, in which the embossing block strippers and the cutters are slidable. Adjustment of the clearer 33 relative to the embossing face 20 and the cutter edge 21, is

provided, and a convenient means is here shown. Rigid with the clearer, and up wardly extending, and slidable in the bed plate l5, are studs 34, secured at their upper end to the plate 32. Set screws in the plate 32, govern the adjustment of the clearer in relation to the face of the bed plate 15, the check nuts 350 being employed to retain the plate 15 in adjusted position.v

I provide four or more studs 31 to insure parallelism with the apron a of the machine, on Which the dough is carried. The adjustment and operation of my device is as folloivs The embossing and cutting elements of the particular design to he produced, is assembled with the clearer and the bed plate, in a single unit as hereinbefore described. The bridges form a part of this unit and are attached to the crosshead 10 by means of the bolts 18 which engage respective sockets 17 in the bridges. 'lhe plate 32 is then adjusted relative to the cutting edges 21. Each embossing block stripper is then adjusted in like relation to its particular block by means of the studs 24 and the check nuts 28 Which are set to retain the adjusted position of the individual strippers. This position being the same in all the strippers relative to the embossing surfaces, 20, the plate 26 is then adjusted by means of studs 27 and the nuts 27() to the particular relation required for the stripper surfaces 29 in relation to the under side of the clearer 33. The device is now ready for operation and as the dough sheet is advanced, the crosshead is reciprocated, and in the first cycle of movements a series of uneinbossed forms lateral with the movement of the dough sheet, are severed, and a corresponding series of enibossed impressions made on the dough sheet in the rear of the cutters and aligned therewith in the direction of the moving dough sheet. As explained the movement of the dough sheet is coordinated with the reciprocation of the crosshead, and in the second and subsequent cycles, the embossed surface of the dough sheet is advanced to be severed by the corresponding cutter in the succeeding cycle. The rapidity of ac tion of the embossing blocks and the cutters is such that no banking of the dough, nor distortion of the embossed pattern is experienced as the respective elements engage the dough sheet. As the dough sheetwith the severed forms and surrounding scrap advances, the severed sections are removed to be panned and the scrap is returned to be incorporated with the dough supply; The bed plate 15 and the clearer 33 are formed With corresponding sockets in which are mounted the compression springs 36, which yieldingly retain the two members in the required relation. As the crosshead together with the attached device, descends projections 37 from the clearer, engage abutments Bil strippers to engage the'dough sheet and pressy thereon While the embossing surface impresses the pattern, and at the same time the surtace embossed in the previous cyle, is severed by the cutters. As the crosshead rises, the embossinnbloclr and theeutters ieave the sheet or dough, the embossing D strippers operating to retain the sheet J against adhesion to vthe block, and the conn bined action ot the clearer and the plungers oit each cutting unit operating to strip the dough `from the cutting edges and retain the severed forni and the resulting scrap dough on the apron. It is thus possible to clear the scrap even when a `j'rarticular embossing bloei; or cutter operates on an imperfect or distorted portion et the dough sheet. ist

tention is called to the `tact that the embossving strippers are not only individually adjustable, but all may be adjusted together which makes it possible to vary the pressure ot the strippers on the sheet of dough after setting, Without individual adjustment.

Among the advantages ot my device are positive action oiE both embossing and cutting units; accurately `embossed and cut forms; positive stripping `from both embossinff and cutting units, and consequent rapid-4 ity oii action; and by means of my device, I

accomplish what now `requires complicated machines, and do it with no adjusting or setting aiter the first set up.

Having thus described `my invention,y I claim:- Y

In an attachment for a dough cutting These are so positioned that at its or embossing machine, including aselements a bed plate, a plurality of embossing blocks and corresponding cutting elements secured to the bed plate; individual stripper elements, slidable lengthwise of the embossing blocks, each yieldingly secured relative to the face ot' its respective embossing block and the bed plate.

2.111 an attachment for a. dough cutting or embossing machine, including as elements a. bed plate, a plurality of embossing blocks andcorresponding cutting elements secured` to the bed plate; stripper elements, slidable 'lengthwise' of the embossing blocks, and

yieldingly secured relative to the respective ,tacos thereof and the bed plate, andmeans iter adjusting the stripping suriace of each stripping element relative to the respective embossing face.

3. In an attachment for a dough cutting or embossing machine, including as elements a bed plate, a plurality of embossing bloclrsvand corresponding cutting elements secured to the bed plate, stripper elements, slidable lengthwise ot the embossing blocks, and yieldinglysecured relative to the re-y spective faces thereof and the bed plate; and means 'for adjusting the stripping surfaces ,ott the stripping elements, individually and collectively relative to the embossing `faces. A
